5、关闭NetworkManager
# chkconfig --level 123456 NetworkManager off

# service NetworkManager stop
Stopping NetworkManager daemon: [ OK ]

1.6、安装 cvuqdisk包，验证grid环境，并修复failed

1、安装cvuqdisk(每个节点)
# CVUQDISK_GRP=oinstall; export CVUQDISK_GRP

# rpm -qa |grep cvuqdisk
cvuqdisk-1.0.9-1.x86_64

# ll /home/grid/grid/rpm
total 12
-rwxr-xr-x 1 root root 8551 Sep 22 2011 cvuqdisk-1.0.9-1.rpm

# ls -l /usr/sbin/cvuqdisk
-rwsr-xr-x 1 root oinstall 10928 Sep 4 2011 /usr/sbin/cvuqdisk

2、验证grid环境
node1->find /home/grid/grid/ -name runcluvfy.sh
/home/grid/grid/runcluvfy.sh

Checking ASMLib configuration.
Node Name Status
------------------------------------ ------------------------
node1 passed
node2 (failed) ASMLib does not list the disks "[VOL2, VOL1, VOL5, VOL4, VOL3]"

node1->./runcluvfy.sh stage -pre crsinst -fixup -n node1,node2 -verbose >> /home/grid/runcluvfy.check

Check: Package existence for "sysstat"
Node Name Available Required Status
------------ ------------------------ ------------------------ ----------
node2 missing sysstat-5.0.5 failed
node1 missing sysstat-5.0.5 failed
Result: Package existence check failed for "sysstat"

Check: Package existence for "pdksh"
Node Name Available Required Status
------------ ------------------------ ------------------------ ----------
node2 missing pdksh-5.2.14 failed
node1 missing pdksh-5.2.14 failed

Result: Default user file creation mask check passed
Checking consistency of file "/etc/resolv.conf" across nodes

Checking the file "/etc/resolv.conf" to make sure only one of domain and search entries is defined
File "/etc/resolv.conf" does not have both domain and search entries defined
Checking if domain entry in file "/etc/resolv.conf" is consistent across the nodes...
domain entry in file "/etc/resolv.conf" is consistent across nodes
Checking if search entry in file "/etc/resolv.conf" is consistent across the nodes...
search entry in file "/etc/resolv.conf" is consistent across nodes
Checking file "/etc/resolv.conf" to make sure that only one search entry is defined
All nodes have one search entry defined in file "/etc/resolv.conf"
Checking all nodes to make sure that search entry is "localdomain" as found on node "node2"
All nodes of the cluster have same value for 'search'
Checking DNS response time for an unreachable node
Node Name Status
------------------------------------ ------------------------
node2 failed
node1 failed
PRVF-5636 : The DNS response time for an unreachable node exceeded "15000" ms on following nodes: node2,node1

（1）其他节点必须执行oracleasm scandisks
# oracleasm scandisks

（2）可以不安装sysstat
# yum --disablerepo=* --enablerepo=c6-media install sysstat -y
